| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| I50.23 | Acute on chronic systolic (congestive) heart failure | Use when documentation specifies acute on chronic systolic heart failure with supporting clinical evidence. |
|
| I50.33 | Acute on chronic diastolic (congestive) heart failure | Use when documentation specifies acute on chronic diastolic heart failure with supporting clinical evidence. |

Clinical Decision Support
Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Essential facts and insights about Acute Chronic Heart Failure
Primary ICD-10-CM Codes for acute chronic heart failure
Decision Criteria
clinical Criteria
- EF <40% and symptoms of decompensation
documentation Criteria
- Explicit mention of 'acute on chronic systolic heart failure'
Applicable To
- Acute on chronic left ventricular failure
Excludes
- Heart failure due to hypertension (I11.0)
Clinical Validation Requirements
- Echocardiogram showing EF <40%
- BNP >400 pg/mL
- Symptoms of decompensation
Code-Specific Risks
- Incorrectly coding as unspecified heart failure
- Failure to document acuity and type
Coding Notes
- Ensure documentation specifies both the type and acuity of heart failure.
I50.33 - Acute on chronic diastolic (congestive) heart failure
Use when documentation specifies acute on chronic diastolic heart failure with supporting clinical evidence.
Applicable To
- Acute on chronic heart failure with preserved ejection fraction
Excludes
- Heart failure due to hypertension (I11.0)
Clinical Validation Requirements
- Echocardiogram showing EF ≥50%
- Elevated BNP levels
- Symptoms of decompensation
Coding Notes
Ensure documentation specifies both the type and acuity of heart failure.

I11.0Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Acute Chronic Heart Failure to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I50.23.
Impact
Clinical: Inaccurate clinical picture of heart function., Regulatory: Non-compliance with coding standards., Financial: Potential for reduced reimbursement.
Mitigation Strategy
Always include EF in documentation for heart failure.
Impact
Reimbursement: May lead to lower reimbursement rates., Compliance: Non-compliance with coding guidelines., Data Quality: Reduces specificity and accuracy of health records.
Mitigation Strategy
Ensure documentation specifies the type and acuity of heart failure.
Impact
Risk of audits due to unspecified heart failure codes.
Mitigation Strategy
Ensure documentation specifies type and acuity.
Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.
